Exposure to electric shock has been associated with an increased risk of developing delayed cardiac arrhythmias and cardiac diseases. We examined whether electric shock patients have an increased risk of developing cardiac disease, cardiac arrhythmias or death compared with the general Danish population.
Matched cohort study.
A nationwide study in Denmark from 1994 to 2011.
We identified 11 462 Danish patients who visited an emergency ward or were admitted to a hospital due to electric shock from 1994 to 2011. Each patient was matched for age and sex with five random controls from the Danish population.
Mortality, cardiac procedures and cardiac diseases following electric shock.
A total of 7390 electric shock patients were seen at an emergency ward and 4072 electric shock patients were admitted to a hospital. The median patient age was 28.6 years (Q1-Q3, 21.3-37.7) for the emergency ward patients and 26.4 years (Q1-Q3, 18.3-37.4) for admitted patients. In both groups, most patients were male (74.0% and 76.8%). Few of the electric shock patients had a record of cardiovascular disease at baseline (364/11 462, 3.2%). The 5-year cumulative incidence of death was 0.47% (95% CI 0.29% to 0.65%) for emergency ward patients and 1.04% (95% CI 0.71% to 1.37%) for admitted patients. No difference in 5-year survival was observed compared with matched controls (emergency ward, p=0.10; admitted patients, p=0.80). Fewer than four patients received a pacemaker within 30 days.
This nationwide study did not demonstrate an increase in mortality among patients seen at hospitals after accidental electric shock compared with a background population. Cardiac procedures and diseases following electric shock were very rare. We suggest that nearly all patients can be discharged safely from the emergency room after electric shock without further observation.
接触电击与发生延迟性心律失常和心脏病的风险增加有关。我们研究了与丹麦普通人群相比，电击患者患心脏病、心律失常或死亡的风险是否增加。
匹配队列研究。
1994年至2011年在丹麦进行的一项全国性研究。
我们确定了1994年至2011年期间因电击前往急诊病房或住院的11462名丹麦患者。每位患者在年龄和性别上与来自丹麦人群的五名随机对照者相匹配。
电击后的死亡率、心脏手术和心脏病。
共有7390名电击患者在急诊病房就诊，4072名电击患者住院。急诊病房患者的中位年龄为28.6岁（四分位间距，21.3 - 37.7），住院患者为26.4岁（四分位间距，18.3 - 37.4）。两组中，大多数患者为男性（分别为74.0%和76.8%）。很少有电击患者在基线时有心血管疾病记录（364/11462，3.2%）。急诊病房患者的5年累积死亡率为0.47%（95%置信区间0.29%至0.65%），住院患者为1.04%（95%置信区间0.71%至1.37%）。与匹配的对照组相比，5年生存率无差异（急诊病房，p = 0.10；住院患者，p = 0.80）。30天内接受起搏器治疗的患者少于4人。
这项全国性研究未显示意外电击后在医院就诊的患者死亡率高于背景人群。电击后的心脏手术和疾病非常罕见。我们建议，几乎所有电击患者在急诊室接受电击后均可安全出院，无需进一步观察。
